The success of unlicensed broadband communication has led to very rapid deployment of communication networks that work independently of each other using a relatively narrow spectrum. For example, the 802.11g standard uses the industrial, scientific, and medical (ISM) band that has a total bandwidth of 80 MHz. This band is divided into 12 partially overlapping bands of 20 MHz. These technologies could become the victims of their own success, since the relatively small number of channels and the massive use of the technology in densely populated metropolitan areas can cause significant mutual interference. This is especially important for high quality real-time distribution of multimedia content that is intolerant to errors as well as latency.
